Season (sets a typical date, weather and temperature for coastal Andhra Pradesh)
Full sunshine (uses the seasonal factor if switched on). Weather applies to the selected day only; the monthly and annual figures use the typical seasonal profile.
Bands are default illustrative clock ranges only, not universal sunrise/sunset. Actual sunrise and sunset above are calculated for the selected location and date; output is exactly 0 whenever the sun is below the horizon.

Assumptions & uncertainty
Modeled estimate, not a measurement. Sun position is calculated astronomically (SunCalc) for the chosen location, date and time zone; irradiance uses a clear-sky model scaled by the sky-clearness and seasonal factors shown, with the loss assumptions listed. Real output depends on weather, shading, equipment and installation. Live production can only be shown from a verified inverter monitoring connection, which this tool does not have.
Model: Kasten and Young air mass, Meinel clear-sky beam, 10% diffuse, isotropic sky, 20% ground albedo; cell temperature = ambient + (NOCT − 20)/800 × irradiance; AC output clipped at the inverter rating. Expect real annual results to differ by ±15% or more.
